temporal_js_polyfill

Loads the TC39 Temporal polyfill for Dart web apps that need to support browsers without native Temporal. Pairs with temporal or temporal_js.

Features

• loadTemporalPolyfill() — injects temporal-polyfill into the page as a <script> tag and resolves once the global Temporal object is available
• Cross-platform safe — on native / VM platforms every symbol is a no-op or a trivially-true constant, so the same main.dart compiles on every target without conditional imports
• Self-hostable — pass a custom src URL to pin a specific polyfill version or serve it from your own CDN

Getting started

dependencies:
  temporal: ^0.0.1
  temporal_js_polyfill: ^0.0.1

Usage

Call loadTemporalPolyfill() once at app startup, before any Temporal types are used:

import 'package:temporal/temporal.dart';
import 'package:temporal_js_polyfill/temporal_js_polyfill.dart';

void main() async {
  await loadTemporalPolyfill(); // no-op on native and modern browsers
  runApp(MyApp());
}

To use a self-hosted or pinned polyfill bundle:

await loadTemporalPolyfill(
  src: 'https://cdn.example.com/temporal-polyfill@1.0.0/index.umd.js',
);

Browser support

The polyfill targets browsers that implement modern JS but lack the native Temporal API (e.g. Firefox, Safari prior to their respective Temporal shipping dates). On browsers with native Temporal, loadTemporalPolyfill() returns immediately without injecting any script.
